Question

The pedigree shows the inheritance of free earlobes and attached earlobes in five generations of a family. Attached earlobes is caused by a recessive allele (f). Half-shaded symbols are NOT used in this pedigree to show carriers of the allele.

Answer 1

Is individual 2 in Figure 14-2 homozygous or heterozygous for free earlobes? Explain.

Answer 2

Answer 3

well do you know the difference between homozygous and heterozygous

Answer 4

one is horizontal and the other is vertical :D

Answer 5

lol

Answer 6

if i give you definitions can you summarize them

Answer 7

sure

Answer 8

The genetics term heterozygous refers to a pair of genes where one is dominant and one is recessive — they're different. Like all words with the prefix hetero, this has to do with things that are different — specifically genes.

Answer 9

Since diploid organisms have two copies of each gene, they can be homozygous or heterozygous at any given genetic locus, or place on the chromosome. Find out what it means to be homozygous, and get some examples of phenotypes that are caused by being homozygous. Chromosomes, Genes and Alleles.

Answer 10

first ones heterozygous second ones homozygous

Answer 11

you mean to say that individual 1 is homozygous recessive and individual 2 is heterozygous, right?

Answer 12

Heterozygous contains 2 different alleles of the same gene while homozygous contains 2 of the same allele

Answer 13

and this all explains the inheritance of free earlobes??

Answer 14

Is individual 2 in Figure 14-2 homozygous or heterozygous for free earlobes? Explain.
read the difference between heterozygous and homozygous then look at the 12-13 are they the same allele?

Answer 15

Is this an exam question or review?

Answer 16

its a practice Q

Answer 17

Okay, look at individual 4. What is her genotype?

In order for her to have that genotype, what allele must've come from each parent?

What phenotypes do the parents show? What genotypes must they have so the genotypes of their offspring are consistent?

Answer 18

"If you look at the different alleles theres shaded and non-shaded 12-13 is shaded so 14 will be homozygous"

Answer 19

okay ignore that, its just so i remember

Answer 20

i will work this one out but i have 3 more q's based on this pic

Answer 21

thanks guys
