True or False? The definition of a multifactorial trait is one in which more than one set of alleles is involved in which the environment plays no role.
There are 2 different alleles for the number of fingers on the hands: 5 finger allele and 6 finger allele. When both the 5 finger allele and the 6 finger allele are present in the same individual, the individual has 6 fingers on the hands. Which allele is dominant?
False. Julie has a genetic disorder. Julie and her husband, Shane, have three children, none of which have the genetic disorder.
Conversely, low-ranking females who are not in such good shape are more likely to produce daughters, because the chances of giving birth to a future dominant male are poor.
Jan. 25, 2021 — Humans are among the few species that lack overt physical indicators of female fertility. One explanation for concealed ovulation in human females is that hiding fertility from males helps females ...
According to popular belief, whether you have a baby girl or boy is purely a matter of chance. And yet, a study published several years ago shows that mothers in stressful jobs, for instance, give birth to more girls than boys. The correlation between such shifts in the offspring sex ratio and the mother's overall state is something ...
Nonetheless, the healthy females do not produce more male than female offspring. As the model demonstrates, other parameters, such as the fact that a large number of males die before reaching sexual maturity, play a central role in assessing reproductive potential.
Bighorn ewes, for instance, give birth to only one lamb a year. Most females mate with the dominant ram, which means many of the other males don't get a chance. Females in a good state often pass on their condition and so can be expected to "to make supermales," as Neuhaus explains. Nonetheless, the healthy females do not produce more male than female offspring. As the model demonstrates, other parameters, such as the fact that a large number of males die before reaching sexual maturity, play a central role in assessing reproductive potential.
Freckles are dominant over no freckles. If a woman with freckles (homozygous) reproduces with a man with no freckles, what are the chances they will have a child with freckles? 100%. A woman who can roll her tongue (dominant) is married to a man who cannot.
Dimples and short fingers are dominant. If a child does not have dimples and has long fingers, then both his parents must also have dimples and have long fingers.
A 9:3:3:1 phenotypic ratio is expected from a dihybrid cross when
In humans, brown eyes are dominant over blue eyes. A brown-eyed woman who has a blue-eyed child has the genotype
